Frequently Asked Questions
Answers to the questions we get most often. Organized by topic — getting started, service methods, turnaround, warranty, international customers, specific platforms, and regulatory framework. If your question isn't here, call us and we'll answer it.
Getting Started
How do I know if you can help with my truck?
We service most diesel platforms from 2007 forward across Cummins, Paccar, MaxxForce, Mack, Volvo, Cat, Detroit, and International. Tell us platform, model year, and what you're trying to solve — we'll confirm coverage during the quote conversation. If we can't help, we'll tell you and often point you to someone who can.
What's the first step?
Request a quote — tell us platform, fault codes if you have them, and operational context. Same-day quote response during business hours. The diagnostic conversation that follows the quote shapes the calibration scope.
How much does it cost?
We don't publish a fixed-price catalog because the right scope depends on the platform and the operational situation. Most calibration projects fall in a predictable range for the platform — we share the range during the quote conversation along with the scope-specific number. No surprises after the work is committed.
Do I need to know fault codes before I call?
Helpful but not required. If you have a recent scan, sharing the fault codes speeds the diagnostic conversation. If you don't, describe what the truck is doing — that's often enough to get started.
Service Methods
Should I ship in, do remote, or schedule on-site?
Depends on your platform, location, and timing. Most owner-operators default to ship-in. Fleet shops with diagnostic tooling default to remote. South Florida fleet customers and large nationwide fleet projects default to on-site. The compare service methods page covers the matrix.
How long does ship-in take?
2–3 days standard turnaround once we receive the ECM. Round-trip including overnight shipping both ways is typically 4–6 business days domestic, 7–10 days international depending on destination.
Can you do remote programming on every platform?
No — remote works on Cummins INSITE-compatible platforms (B6.7, ISB, ISC, ISL, ISM, ISX, X15) and Paccar Davie4-compatible platforms (PX series, MX-11, MX-13). Legacy Cat, older MaxxForce, and some Detroit configurations need ship-in. We confirm compatibility during the quote.
Where does on-site service cover?
South Florida (Broward, Miami-Dade, Palm Beach, Monroe) with no travel premium. Nationwide for larger fleet projects (20+ trucks at a single yard) with travel quoted separately. International on-site is rare and only for very large fleet projects.
Turnaround And Timing
Can you do same-day work?
Remote sessions can typically schedule same-day for urgent situations. Ship-in inherently has shipping logistics — overnight in, work happens, overnight out — so the physical minimum is 2–3 business days even with maximum priority.
What's the longest turnaround I should expect?
Standard ship-in is 2–3 days in shop. Complex fleet projects with mixed-platform requirements can stretch to a week. International round-trips depend on customs clearance. We'll be specific about expected timing during the quote conversation.
Will my truck start without the ECM?
No. The ECM is the engine's brain. Plan for the truck to sit during the ship-in window. For fleet customers, work through ECMs sequentially so the fleet stays operational.
What if I need the truck back faster than standard turnaround?
Tell us during the quote conversation. We can prioritize at no premium when shop capacity allows. We'd rather be honest about timing upfront than have you waiting longer than expected.
Warranty And Support
What's the warranty?
Our calibration work carries a limited warranty against calibration-related failures for the warranty period stated in your service confirmation. If something doesn't hold up, we reflash at no charge. The warranty doesn't cover hardware failures, third-party labor, or operational damages — calibration only.
What if something goes wrong during reinstall?
Call us. Most reinstall issues — check engine light, no-start, dash code — are diagnostic conversations over the phone. We've seen every variation of missed connector, loose ground, and reversed harness routing.
What if the same problem comes back?
Submit a service ticket. Recurring patterns sometimes indicate operational factors we didn't capture in the original diagnostic — a duty cycle that changed since the original quote, a hardware issue masking as a calibration issue, or a calibration adjustment that needs refinement. We work through it.
Do you offer ongoing support after the initial work?
Yes. For fleet customers, we typically operate under recurring relationships with documented platform-specific calibration baselines. Service tickets, remote diagnostic sessions, and follow-up calibration adjustments are part of the ongoing relationship rather than separate transactions.
International Customers
Can you work on trucks outside the US?
Yes. We've shipped to and from Mexico, Panama, Central America, the Caribbean, South America, Africa, Asia-Pacific, and Europe. The testimonials and case studies page documents specific international work.
How do customs work?
Ship the ECM with customs declaration noting 'used automotive electronic component for repair and return to sender' with fair-market replacement value. We provide return customs paperwork. Most international round-trips clear customs without delay.
Can you handle export-destined trucks before they ship out?
Yes — and this is often the cleanest path. Trucks coming to South Florida for export shipment can have ECMs programmed at our shop before reaching the port. Carlos V.'s testimonial documents this workflow with F-750 export trucks.
What time zones do you work in?
Eastern US business hours (Mon–Fri 8 AM–6 PM ET) for primary support. For international customers in distant time zones, we coordinate scheduled call windows in advance. Email and form responses come within one business day at the latest.
Specific Platforms
Do you work on Cummins X15?
Yes. X15 is one of the platforms we service most frequently. Full INSITE diagnostic coverage, full calibration library. Ship-in, remote, or on-site all work on X15.
Do you work on Cat C13/C15 ACERT?
Yes. Cat truck engines in the ACERT generation are a regular part of our work, particularly for oilfield service trucks and sustained-idle applications where the ACERT calibration fights duty-cycle reality. Ship-in primary, since Cat ET diagnostic ecosystem doesn't support remote calibration loading well.
Do you work on MaxxForce platforms?
Yes. MaxxForce DT, 7, 9, 10, 11, 13, 15 — the EGR-only platforms that became operationally problematic at scale. EGR delete is common on these platforms; the testimonials page documents specific cases.
Do you work on the A26 platform?
Yes. The A26 replaced legacy MaxxForce 11/13 around 2017 and shares calibration ecosystem with Cummins X15. We treat it as part of the Cummins family for service workflow purposes.
Do you work on older trucks without DPF?
Yes — EGR delete, performance tuning, fault code resolution, and calibration work apply across the legacy fleet population. Older platforms (Cummins ISC pre-2007, MaxxForce DT, Sterling MBE platforms) remain in active service across many fleets.
What about electric trucks?
No — we don't work on electric platforms. Our work is calibration of diesel engine control modules. Electric powertrain calibration is a different ecosystem.
Regulatory And Legal
Is DPF delete legal?
It depends on jurisdiction and use case. In the US, removing emissions controls on vehicles operated on public roads is prohibited under the Clean Air Act. Off-road use, off-highway operations, and export to markets with different regulations have different frameworks. We offer delete services for off-road and export use only. The off-road and export use explained page covers the regulatory framework in detail.
Will delete cause a vehicle inspection failure?
In jurisdictions with emissions inspections, yes — vehicles with delete modifications won't pass an inspection that verifies emissions controls are present and functional. Customers in jurisdictions with emissions inspections should understand this before considering delete services.
What if I need to maintain compliance?
Emissions recalibration and performance tuning work within the compliance envelope and can address most operational pain points without delete-class modifications. Tell us during the quote conversation that compliance maintenance is required — we'll shape the scope accordingly.
